Ecology is the study of interactions among organisms and their environment.
Explanation:
The definition of ecology aligns with option c: the study of interactions among organisms and between organisms and their environment. This scientific field aims to understand the distribution and abundance of living organisms, the interactions between these organisms and their surroundings, and how such interactions are affected by natural and human-made changes to the environment.
Besides, the other options given represent the concepts related to but not accurately defining ecology. For example, option a refers to environmentalism, while option b refers to recycling, and option d typifies sustainable living.

A genetic factor exhibiting a trait even in the presence of alternative forms is described as a dominant allele. Dominant alleles express over recessive genes, as exhibited in the height trait of pea plants.
Explanation:
A genetic factor for a trait that is always expressed when present is referred to as a dominant allele. In genetic terms, alleles are variations of a gene. In a pair of alleles, one can be dominant and the other recessive. When an individual possesses both the dominant and the recessive allele, the trait associated with the dominant allele gets expressed. For example, for the gene concerning height in pea plants, the allele for tallness is dominant over the allele for shortness. Thus, when a plant inherits the tall and short alleles together, the tall trait is expressed due to the dominance of the tall allele.

A theory is an accepted explanation of an observed phenomenon supported by empirical data, whereas the scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses.
Explanation:
1.) A theory is an accepted explanation of an observed phenomenon supported by empirical data. For example, the theory of evolution is an accepted explanation of the observed changes in species over time, based on a wealth of empirical evidence from biology, geology, and other fields. 2.) The scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses. This process includes making an observation, asking a question, doing research, constructing a hypothesis, testing the hypothesis through experimentation, analyzing data, and drawing a conclusion.
